Just my 2 cents. If this is your first engine, build it as stock as possible. maybe ported heads, a more aggressive cam, headers, dual exhaust, better intake and carb, IE bolt on stuff. Unless you have someone very knowledgeable to guide you, internal engine mods can get expensive and troublesome in a hurry. will your valves clear your pistons with the popup on the piston and the high rise of your cam. do you have the correct length push rods etc. Not trying to scare you, just as with most things you have to learn to crawl before you can run.
